Hi Casey Thank you for your help. We fixed the problem on the same day but then I forgot to post back the solution here... So basically we had 2 problems: -the barbican secret key payload need to be exactly 32 Bytes -the ceph.conf need a user id (username not ok): rgw keystone barbican user = <rgwcrypt_uid>
And of course this rgwuser need the read permissions on the barbican secret.

In this case, the keyid is itself a url, so rgw is sending a request to "https://barbican.service.xxx.ch/v1/secrets/https://barbican.service.xxx.ch/v1/secrets/ffa60094-f88b-41a4-b63f-c07a017ad2b5";. It's hard to tell without logs from barbican, but I suspect that it's trying to interpret the slashes as part of the request path, rather than part of the keyid. So I would recommend using keyids of the form "ffa60094-f88b-41a4-b63f-c07a017ad2b5", but would also consider the lack of url-encoding to be a bug. I opened a ticket for this at http://tracker.ceph.com/issues/39488 - feel free to add more information there. Barbican log output showing the request/response would be helpful!
